A 10 km climb from the small roundabout in Châtillon, it's more like 14 km from the Nantua road or the center of Bellegarde. The gradient is fairly steady, ranging from 5.5% to 7.2%, with about ten small steep sections at +8.5%. Very quiet, with very few cars. The road is generally in good condition, but nothing more. There are some beautiful views along the way.

Small pass, but no way to drive into the valley on the D39. Road closed. I didn't even try.

Second pass for today. Pass elevation 1144 m above sea level. Long climb, basically from Saint Germain to here. A total of about 700 m elevation gain and 12 km. The gradient is only 4-6%, but with 20 kg of luggage, everything is difficult ;) Here, too, the weather was still quite cool in very early April. Partly rain, partly windy.
